To aZl w'hom'z't may concern:

-Be it' -known that I, ALBERT HENRI 'fMmGLEfi -Za subject of the King of 'lGreat B'r'itain afrid Ireland, and residing at fWarple xllVay, Atbn Vale, in the county of Middle- "sex'; England, have invented certain new and useful. Improvements in and Relating to Time-Fuses for Shells, of which the fol- {lowingisi a specification. 10. This invention relates to time fuses fol V shells'of the" kind in which the timing is feifected by'punching a lead or like covered fuse at ap'oint more or less distant from its ipointlofconnection with the space communicating with theprimer, according to the *"ti'm'e'it jdieSiI'd to lapse between the mome'nt oflfiiiing' andthat of explosion. f It isik'n own to -place'the fuse composition of ajtim'efuse-in two adjacent grooy'es and [to separate the two adjacent portions of the .jfus'e" fromeachother, with the exception of.

with an annular recess 12 or with a portion of such recess, adapted to receive a lead covered or similar fuse 0 bent back onitself in the form of a hairpin, the two ends 0 0 of the fuse being inserted into substantially radial holes leading to the spaces d d communicating with the primer and the explosive respectively, and its two adjacent portions which lie in the annular recess being separated from each other by an incomplete bipartite flat ring e fitting in a groove provided in the bottom of the recess. The recess 12, the radial depth of which at and in the proximity of the bend of the fuse is made greater than in the remaining portion thereof for the purpose of being able to bendthe fuse back on itself without interfering with the continuity of the ring, is covered by a sleeve f which is adapted to be rotated on the fuse holder a and to carry with it the separating ring 6, for instance through the intermediary of a spring'g secured to the sleeve f and carrying pins g arranged to slide in holes f provided in the sleeve f and to engage in notches e provided in the separating ring 6. At the oint 'opf the separating ring 6, the sleeve'f is provided with a hole f of the required dimension to permit' of a punch being inserted therein for the purpose of laterally punching the two adjacent portions of the fuse.

The rotary sleeve fl and the fixed fuse holder a are provided with an index f and with graduations h respectively for the purpose of indicating the timing of the fuse which is determined bythe position of-the' sleeve relatively to the holder. The recess in which the fuse is mounted is preferably 7 beveled as shown at b and the portions of the rotary sleeve facing the beveled portions of the recess are preferably provided with holes f to allow the gases to escape.

The end 0 of the fuse preferably terminates into a ring 6 for the purpose of direct ing the flame downward through the hole 2' of the ring.

The operation ofthe fuse hereinbefore described is as follows The rotary sleeve 7 is turned on the fixed holder a until the index f thereon comes to lie in front of the graduation corresponding to the required timing. While the sleeve is thus rotated it carries with it the separating ring e between the two adjacent porablemember for covering-the'=,aclj acent'parts tions of the fuse 0, whereby the position of the punching hole f providedin the sleeve f and of the incomplete p( )rtik n e o'f the separating ring- -eis altered relatively to the' e? of the separating. ring-,eiand across th; (provided the fuse "has been punched at: this. p oint and through. the ad;-

having; se d her n-la d extending from the space d communicating with th'e primer ,to the i incomplete "portion passage jacent portion of the fuse lying underneath to the spaced?v communicating with the ex: plosive. in the shell, is/also; altered.

It will thus be; Seen that in. the event of i the fuse; having: been .punclredin' a wrong position, the'same can alwaysbe punched againlin another position and beefliciently used in spitev of the previous punching, since the only means of communication. between the two separate compartments containing the-adjacent portions-of the fuse is the in,- complete portion 6 .of the separating ring 6, so/thatwhen the; latter is-moved around until theincomplete portion comes to-liejinthe' position; corresponding to the proper timing, the portions; previously -wronglyg punched are now separated from each; other by the interposingringe; V v It will alsoibe seen that if the lead cov-, ered fusehas not been effectively punched,

the same will still be operative-although the] time will not be correct, since in this case the burning. of the fuse will continue along holder, fa ,recessyformedton' theperipheryjof I i the fuse holdery a covered fuse mounted id V the twocom'plete 'ad aeent portionsof the fuse between its. two ends.=
